The objective of the present study was to evaluate the impact of a snack bar on some health indicators associated with diet (plasma antioxidant capacity, lipid profile, vitamin A profile (retinol and carotenoids)) and on the nutritional status (impact on energy and nutrients consumed) in a group of upper level students.
A blind randomized controlled clinical study of healthy adults, which was carried out with the approval of the ethics committee of the Centro de Investigación en Alimentación y Desarrollo, A.C. (CIAD, A.C.) with registration CE/001/2017. The intervention was carried out in a public university in Mexico from January to April 2017. Each subject signed an informed consent form. This study lasted 30 days (4 weeks), where each participant consumed daily a snack bar irradiated with UV-C. The participants were personally interviewed by the research team with a structured selection questionnaire. Thirty subjects who met the inclusion criteria were recruited, 15 of them men and 15 women. Through a simple randomization process, the participants were assigned in 3 groups of 10 people each with 5 women and 5 men, subsequently treatments (without treatment, pineapple snack bar, or mango snack bar) were randomly assigned. The outcomes between groups were analyzed with one way ANOVA, with a P-value of 0.05 or less when there was statistical significance, using statistical software. The participants, and the laboratory technicians were blinded to the treatment assignments until the conclusion of the trial.
